After her sister dies, Meara Deleaney invites her bereaved nephew, Jackson, to accompany her on a book tour to Canada's Atlantic provinces. Fearful of leaving the security of her apartment, Meara bolsters her courage by recalling the imaginary dragons she and her sister slew as children behind the hollyhock hedge.

As they travel in a motorhome from park to park and bookstore to bookstore, Meara and Jackson are unaware of the manipulating forces intent on preventing their return home. They do, however, realize they are being stalked and therefore welcome the company of another touring author, criminology professor Bartholomew Wolfe.

A long-standing professional relationship between the authors builds to romance and a persuasive invitation to seek shelter at the professor's lodge. However, to reach the lodge, Meara—now accompanied by her nephew, niece and mother—unsuspectingly travels through a portal which exits in a future dimension near a fortress.

From there, the family is escorted under guard through dangerous territory to a lodge where metaphorical dragons lie in wait, and security comes at a price.
